title: Benign adrenal hemangiomas may mimic metastases on PET.
abstract: CT or MRI are utilized in the initial evaluation of adrenal incidentalomas; however, overlap exists between benign and malignant lesions on these examinations. The American College of Radiology recommends PET scans to complement CT and MRI for patients with adrenal masses and a moderate-to-high likelihood of neoplastic disease. We present images of a PET-avid adrenal lesion in a patient with pulmonary and pancreatic neoplasms that mimicked metastasis, but was found to be a benign adrenal hemangioma on surgical resection. The use of PET for adrenal tumors, specifically adrenal hemangiomas, will be reviewed.
